Have you ever seen those people on the news scratching their head after they built their home right on the edge of the sea - on a foundation of sand? They can never quite seem to figure out why their house fell into the ocean one day unexpectedly.
This is the kind of day I’m having at work. Multiple failures are occurring across many computers affecting hundreds of applications. Everyone seems befuddled that so much stuff is broken or unavailable. There is a common denominator at play here. We trusted a shared disk that supports dozens of computers (maybe hundreds). This is our version of a sand foundation. Once it becomes unstable, our whole house of cards starts tumbling down very quickly too.
I now find myself wishing I’d taken two weeks off, not one.

Single point of failure is not good.
